Taw qhia
3-Chloro-2-hydroxy-5-(trifluoromethyl) pyridine yog cov organic compound. Cov hauv qab no yog kev qhia txog nws qhov xwm txheej, kev siv, kev tsim khoom thiab cov ntaub ntawv kev nyab xeeb:
1. Xwm:
Cov tsos mob: 3-Chloro-2-hydroxy-5-(trifluoromethyl) pyridine yog xim tsis muaj xim rau daj ntseg daj.
- Solubility: Nws yuav luag insoluble hauv dej, tab sis soluble hauv cov kuab tshuaj organic xws li ether, methanol thiab methylene chloride.
- Cov khoom siv tshuaj: Nws yog cov tshuaj alkaline uas ua rau cov tshuaj tiv thaiv tsis zoo tiv thaiv cov kua qaub. Nws kuj tseem siv tau los ua fluorinating reagent los qhia cov pab pawg trifluoromethyl rau hauv lwm cov organic tebchaw.
2. Kev siv:
- 3-Chloro-2-hydroxy-5-(trifluoromethyl) pyridine feem ntau yog siv rau hauv cov organic synthesis cov tshuaj tiv thaiv raws li catalyst lossis reagent. Piv txwv li, nws tuaj yeem siv los tsim cov carbon-fluorine bonds thiab cov tshuaj tiv thaiv amination.
- Nws kuj tuaj yeem siv los ua cov khoom pib lossis nruab nrab hauv kev sib xyaw tshuaj tua kab.
3. Txoj kev:
- Ib txoj kev npaj siv feem ntau yog ua rau pyridine nrog trifluoroformic acid thiab sulfuric acid los tsim 3-chloro-2-hydroxy-5-(trifluoromethyl) pyridine.
4. Cov ntaub ntawv kev nyab xeeb:
- 3-Chloro-2-hydroxy-5-(trifluoromethyl)pyridine yuav tsum tau zam thaum lub sij hawm cia thiab siv nyob rau hauv kev sib cuag nrog cov oxidants muaj zog thiab combustibles kom tsis txhob muaj hluav taws kub los yog tawg.
- Tej zaum nws yuav muaj kev cuam tshuam rau ntawm daim tawv nqaij, qhov muag, thiab ua pa, thiab cov cuab yeej tiv thaiv tsim nyog xws li hnab looj tes, tsom iav, thiab cov cuab yeej tiv thaiv ua pa yuav tsum hnav thaum ua haujlwm.
- Thaum siv lossis tuav cov khoom sib xyaw, nws yuav tsum tau ua nyob rau hauv qhov chaw uas muaj cua zoo thiab tsis txhob nqus los yog nqus tau. Tom qab kev kho mob, thaj chaw muaj kab mob yuav tsum tau muab ntxuav kom huv.
